We have an old classic Hunter fan (22272-003 L) which for a variety of reasons we plan to replace with a Fanimation Levon. The Hunter is mounted on a 72" downrod from a very high sloped ceiling. I was hoping that I could just swap out the fans on the same downrod, but the Fanimation's downrod is 1" unthreaded (it connects with a clevis pin and a set screw). I believe the Hunter's downrod is 3/4" and threaded, with a hole for a pin (can someone confirm?).
One idea I had was to get a sleeve with a 1" OD and 3/4" ID, drill holes in it for the clevis pin and the set screw, and just mount the new fan onto the old rod with this sleeve as a spacer. Does this sound reasonable (and safe)? Is there any chance the clevis pin hole in the Hunter downrod will be suitable (ie, the right diameter, the right distance from the end of the rod)? Or any other suggestions?
Thanks in advance. David

Just leave the old fan up. The new fan may look better, but the old fan is actually much better than today's ceiling fans. Or if you don't want to, sell it to one of the collectors here. You'll make money out of it. Please don't throw the old fan out.

If you're really set on replacement, 3/4"-to-1/2" (inside diameter) downrod adapters do exist.

You'll make money out of it. Please don't throw the old fan out. I respect the Hunter (it is one of 3 of the era in our house), but it was never large enough for the space, and it has an annoying electrical buzz that I'm pretty sure is a motor winding problem. While this kind of repair is probably within my skillset, I don't know if I will have time to work on it; I certainly won't for the next several months at least, and we need a working fan now. (I'm in the tropics, and summer is coming fast.) In any event, it won't get thrown away. I haven't run the replacement fan yet, but I've looked it over carefully and the build quality seems to be excellent. Andrew, the inner diameter on the new fan is 1", not 1/2"; it uses a bigger downtube than the Hunter. I've not seen any adapters anywhere going from 3/4" to 1". Even if I had, the idea of just using the existing smaller tube in the larger fan mount but stabilizing it with a sleeve or bushing is attractive because it seems simple, with few extra possible failure points. Maybe too simple? In any event, thanks for your suggestions. |

There are plenty of fan collectors here that would be willing to trade your current Hunter Original for a fully restored one. If you really do want to replace it though, I guess the Fanimation might not be such a bad choice (better than some low-end Hampton Bay)! Andrew, the inner diameter on the new fan is 1", not 1/2"; it uses a bigger downtube than the Hunter. I've not seen any adapters anywhere going from 3/4" to 1".

Maybe too simple? In any event, thanks for your suggestions. I'd try going to my local Home Depot of Lowes, and looking in the plumbing section for pipe adapters. I believe I've seen 3/4" to 1" before. |

1. The Hunter actually moves more air than the Fanimation. The Hunter is rated at 8,000-8000, the Fanimation is 5,600. If you want more airflow you need a commercial rated fan. The best option is the Northwest Envirofan Gold Line rated at 34,000 or the Platinum line rated at 41,000. And they use the same downrod size at the Hunter. They run about $150-200 and they dont need as long of a downrod as a residential fan.
2. Your original suggested for a downrod coupler is safe but doing the wiring will be difficult unless you remove the downrod at the ceiling.

The Fanimation is actually closer to 7000, but point taken. We can't run the Hunter at top speed because of the noise unless/until we repair it.
The Envirofan is interesting, but too late now, since we have the Fanimation.
OK, so the other question I had was about the Hunter downrod itself, namely will it have a hole for the clevis pin? (I could answer this by removing the fan, but I was hoping not to do that until I was ready to put up the replacement.) On our fans all I see from the outside is a set screw, not a pin.
Thanks again for all your help.

The existing 3/4" rod probably will not, but you can drill holes through it easily enough.

Personally I would return the Fanimation and buy the Envirofan.
Andrew is correct, there wont be a hole, you can drill one.
Personally I think this will look odd, the downrod and canopy wont match the fan. I would remove the existing downrod and canopy and replace them with those from Fanimation. Drilling the hole and splicing the wires up on a ladder isnt easy. But it will work.

I see Fanimation's site says 6900 cfm. Other sites that sell the fan say 5600.
Fanimation is a good company.

The Fanimation downrod plus sloped ceiling adapter will cost me at least $125, plus another $50 for shipping (I am in Hawaii), and reinstalling up at the top of an 18' ceiling is not going to happen, at least not by me. I've probably had the new fan sitting here long enough that I can't return it, but even if I could that would be another $50 by cheapest route.
In retrospect it might not have been the wisest purchase, but I had a quick shot at getting the fan at a very attractive price ($360 including shipping) and jumped on it. Somehow I had in mind that Fanimation downrods were 3/4", but obviously I was mistaken. Oh well.

I tried one hardware store today and didn't see anything obvious. I'll keep looking. I suppose another possibility would be to get a couple of inches of tubing with the right inner and outer diameters and get my local machine shop to put threads in one end and pin holes in the other. Any idea of what the thread standard used on the Hunter rods are? (NPT? NPS? BSP?) I think at 3/4" diameter they all have the same pitch (14 threads/inch), so maybe just a straight inner thread at 14tpi will do the job regardless.

They are NPT 3/4 I.D. 1". O.D. Pipes. AFAIK, The fanimation pipe is the same diameter except they call it 1", using the O.D. instead of the I.D. I have put up a couple of recent Fanimations and this was the case. All you may have to do is thread the end of the Fanimation pipe and get a 3/4"- 3/4" black iron pipe coupler, drill it on both ends and put a 1/4-20 set screw in it. Cut the wires inside the switch housing on the Hunter and unscrew the motor from the pipe... be careful... you may or may not realize it weighs 50 pounds and has oil in it. Then you have your wire you need. Screw the fanimation pipe to the hunter pipe, then attach your wires (you will not need the safety cable... cut it) and hold the fanimation motor up and put the pin through the motor coupler.

Or alternatively, drill the existing hunter pipe for a pin.
